| titleOfInvention | A kind of synthetic method of 4-iodophenoxyacetic acid |
| abstract | The invention discloses a method for synthesizing 4-iodophenoxyacetic acid, comprising the following steps: 1) dissolving phenyloxyacetic acid and sodium iodide in methanol aqueous solution, stirring and maintaining the temperature at 25-30° C.; 2. ), add sodium hypochlorite aqueous solution dropwise with stirring at 25～30°C; 3) after the dropwise addition is completed, the temperature is raised to 30～36°C, and the reaction is stirred for 1～2h; 3. Precipitate 4-iodophenoxyacetic acid; 5), cool to 10° C., stand for 0.5-1 h, filter, wash with cold water and then dry to obtain the finished product 4-iodophenoxyacetic acid. In the present invention, phenoxyacetic acid and sodium iodide are used as substrates in methanol aqueous solution, and sodium hypochlorite is added dropwise to prepare 4-iodophenoxyacetic acid. |
